Cable foil removal device

Description

BACKGROUND OF THE DISCLOSURE Technical Field

[0001] The present disclosure relates to a removal device of cable foil according to the preamble of claim 1, and in particular, to a removal device of cable foil, in which an outer insulating member and foil of an electric wire (including a cable) are cut by a foil cutting unit and the cut foil is stripped by a foil stripping unit, thus reducing working time for removing the foil and enabling the outer insulating member and foil of the electric wire to be uniformly removed.Background Art

[0002] Generally, an electric wire collectively refers to a line used to send power or electric signals.

[0003] The electric wire is formed such that at least one metal wire is surrounded by an insulating member, and an outer insulating member is formed to surround the outside of the insulating member again. Here, metal foil for shielding EMI is formed between the insulating member surrounding the metal wire and the outer insulating member surrounding the outside of the insulating member.

[0004] In order to use the electric wire configured as such, after the outer insulating member and the metal foil are removed from the electric wire, the metal wire should be coupled to metal wire of another electric wire or should be connected to a power terminal of a power source.

[0005] Conventionally, since the outer insulating member and the metal foil are removed using the manpower of a worker, a working time increases and it is difficult to uniformly remove the outer insulating member and the metal foil.

[0027] Hereinafter, a removal device of cable foil according to a preferred embodiment of the present disclosure will be described.

[0028] As shown in FIGS. 1 to 4, the removal device of the cable foil according to the present disclosure includes a fixing member 100 configured to fix an electric wire 10, a foil cutting unit 200 which is disposed adjacent to the fixing member 100 to cut foil of the electric wire 10 fixed by the fixing member 100, and a foil stripping unit 300 configured to strip the foil of the electric wire 10, which is cut by the foil cutting unit 200, from the electric wire 10.

[0029] First, the fixing member 100 is a member formed in the shape of an approximately rectangular box, and is formed such that upper and lower portions thereof are separated from each other. The upper portion thereof is rotatably coupled to the lower portion in the form of a hinge. Here, a fixing hole having a diameter corresponding to that of the electric wire 10 is formed at a portion where the upper and lower portions of the fixing member 100 come into contact with each other. Thus, as the electric wire 10 is introduced into the fixing hole, the fixing member 100 fixes the electric wire 10. An operation where the fixing member 100 fixes the electric wire 10 is as follows: after the upper portion of the fixing member 100 is rotated upwards, the electric wire 10 is positioned in the fixing hole formed in the lower portion of the fixing member 100 and then the upper portion of the fixing member 100 is rotated downwards, so the electric wire 10 is fixed to the fixing member 100. In this case, a portion of the electric wire 10 from which the foil is to be stripped is fixed to be positioned on the foil cutting unit 200 and the foil stripping unit 300.

[0030] Meanwhile, the foil cutting unit 200 includes a first rotating member 210 which is rotatably disposed adjacent to the fixing member 100 to be rotated by a connected first rotating shaft 220, a first rotation motor 230 which is connected to the first rotating shaft 220 to rotate the first rotating shaft 220, a pair of cutting blades 240 which are slidably installed on the first rotating member 210 so that the blades come into contact with or are released from the electric wire 10 by a sliding movement, and a distance adjustment means which slides the cutting blades 240 to adjust a distance between the pair of cutting blades 240.

[0031] The first rotating member 210 is a rectangular structure in which a hollow portion is formed and which has a predetermined thickness, and is rotatably installed adjacent to the fixing member 100 such that a first side thereof faces the fixing member 100. Here, a second side of the first rotating member 210 is connected to the first rotating shaft 220, and the first rotating shaft 220 is connected to the first rotation motor 230, so the first rotating member 210 is rotated by driving the first rotation motor 230. In this regard, the first rotating shaft 220 and the first rotation motor 230 are installed to be connected to each other by a belt pulley. However, without being limited thereto, the first rotating shaft 220 and the first rotation motor 230 may be connected in a shaft coupling manner.

[0032] Furthermore, extension portions are provided on both sides of the first rotating member 210 to extend outwards from the first rotating member 210, and a pair of cutting blades 240 is installed on each extension portion. The cutting blade 240 is formed of a plate-shaped metal having a predetermined thickness, and has on a first end thereof a cutting edge configured to cut an outer insulating member and the foil of the electric wire 10. The cutting blade 240 is slidably installed on each extension portion of the first rotating member 210. Thus, when a distance between the cutting blades 240 is narrow, the cutting edge of the cutting blade 240 comes into contact with the outer surface of the electric wire 10. When a distance between the cutting blades 240 is wide, the cutting edge of the cutting blade 240 comes away from the outer surface of the electric wire 10. If the first rotating member 210 is rotated in a state where the cutting edge of the cutting blade 240 configured as such comes into contact with the outer surface of the electric wire 10, the cutting blade 240 is rotated along with the first rotating member 210, thereby cutting the outer insulating member and the foil of the electric wire 10.

[0033] Furthermore, the distance adjustment means includes a sliding member 250 which is formed to surround the first rotating shaft 220, is installed to slide along the first rotating shaft 220, and is tapered on an outer surface thereof towards the first rotating member 210 such that a diameter thereof is reduced towards the first rotating member 210, a distance adjustment member 260 which is installed on the first rotating member 210 such that a central portion thereof is rotatable, is installed such that a first side thereof is connected to each cutting blade 240, and is installed such that a second side thereof is in contact with the tapered outer surface of the sliding member 250, a slide block 270 which is installed to be connected to the sliding member 250, a slide driver 280 which is connected to the slide block 270 to slide the slide block 270, and a contact wheel 290 which is rotatably installed on the second side of the distance adjustment member 260 to come into contact with the tapered outer surface of the sliding member 250.

[0034] The sliding member 250 is a conical member in which a hollow portion is formed, and the first rotating shaft 220 is installed to be fitted into the hollow portion of the sliding member 250. Here, the sliding member 250 is disposed such that a vertex thereof faces the first rotating member 210. Thus, the outer surface thereof is tapered towards the first rotating member 210. The slide block 270 is connected to the lower portion of the sliding member 250, and the slide block 270 is connected to the slide driver 280, so the slide block 270 slides by the driving of the slide driver 280. Thereby, the sliding member 250 connected to the slide block 270 slides along the first rotating shaft 220.

[0035] A pair of distance adjustment members 260 is provided, so the central portion of each distance adjustment member 260 is rotatably installed on each extension portion of the first rotating member 210. Further, the first side of each distance adjustment member 260 is connected to each cutting blade 240, and the second side thereof is installed to be in contact with the tapered outer surface of the sliding member 250. Here, the contact wheel 290 which is rotatably installed on the second side of each distance adjustment member 260 is provided, so the contact wheel 290 comes into contact with the tapered outer surface of the sliding member 250.

[0036] An operation of the distance adjustment means configured as such will be described with reference to FIGS. 3 to 5. The slide block 270 is slid by the operation of the slide driver 280, and thus the sliding member 250 connected to the slide block 270 slides along the first rotating shaft 220. If the slide driver 280 is operated to move the sliding member 250 to the left of FIG. 3, the second side of the distance adjustment member 260 moves upwards along the outer surface of the sliding member 250 by the movement of the contact wheel 290. Thereby, the first side of the distance adjustment member 260 is moved downwards, so the cutting blade 240 connected to the first side of the distance adjustment member 260 is moved downwards. This describes the distance adjustment member 260 and the cutting blade 240 located on the upper side of FIG. 3, and the distance adjustment member 260 and the cutting blade 240 located on the lower side of FIG. 3 are moved in a direction opposite to that of the above description. As such, the cutting blade 240 is moved up and down by the distance adjustment means, thus adjusting the distance between the cutting blades 240. By this operation, the cutting edge of the cutting blade 240 comes into contact with or is released from the outer surface of the electric wire 10.

[0037] Meanwhile, the foil stripping unit 300 includes a second rotating member 310 which is rotatably disposed inside the first rotating member 210 to be rotated by a connected second rotating shaft 320, a second rotation motor 330 which is connected to the second rotating shaft 320 to rotate the second rotating shaft 320, a stripping member 340 which is rotatably installed on the second rotating member 310 to come into contact with the outer surface of the electric wire 10, a third rotating shaft 350 which is connected to the stripping member 340, and a third rotation motor 360 which is connected to the third rotating shaft 350 to rotate the third rotating shaft.

[0038] The second rotating member 310 is a circular plate of a predetermined diameter installed in the hollow portion of the first rotating member 210, is disposed such that a first side thereof faces the fixing member 100, and is connected at a second side thereof to the second rotating shaft 320 to be rotated by the driving of the second rotation motor 330 connected to the second rotating shaft 320. In this case, the second rotating shaft 320 may be formed to have a diameter smaller than that of the first rotating shaft 220, so the second rotating shaft may be installed in the first rotating shaft 220. Here, the second rotating shaft 320 and the second rotation motor 330 are installed to be connected to each other by the belt pulley. However, without being limited thereto, the second rotating shaft 320 and the second rotation motor 330 may be connected in a shaft coupling manner.

[0039] The stripping member 340 is a cylindrical member having a predetermined diameter, and is rotatably installed on the first side of the second rotating member 310. Here, the stripping member 340 is rotatably installed at an outer point which is distant from the center of the second rotating member 310 by a predetermined distance. This is for a side of the stripping member 340 to come into contact with the outer surface of the electric wire 10. The side of the stripping member 340 may be formed in an uneven shape.

[0040] The stripping member 340 may be connected to the third rotating shaft 350, and the third rotating shaft 350 may be connected to the third rotation motor 360, so the stripping member 340 is rotated by the rotation of the third rotation motor 360. Here, the stripping member 340 is rotated in a direction opposite to the rotating direction of the second rotating member 310.

[0041] Hereinafter, an operation of the removal device of the cable foil according to the present disclosure will be described in detail with reference to FIGS. 5 to 7.

[0042] If the electric wire 10 from which the foil is to be removed is fixed by the fixing member 100, the distance between the cutting blades 240 is reduced by the distance adjustment means, so the cutting edge of the cutting blade 240 comes into contact with the outer surface of the electric wire 10 (see FIG. 5).

[0043] Subsequently, as shown in FIGS. 6 and 7, the first rotating member 210 is rotated in a direction shown by arrow A by the rotation of the first rotation motor 230, and thereby the cutting blade 240 installed on the first rotating member 210 is rotated. If the cutting blade 240 is rotated as such, the outer surface of the electric wire 10 coming into contact with the cutting edge of the cutting blade 240 is cut.

[0044] If the outer surface of the electric wire 10, i.e. the outer insulating member and the foil of the electric wire 10 are cut by the cutting blade 240 as such, the second rotating member 310 is rotated by the operation of the second rotation motor 330. Here, the second rotating member 310 is rotated in a direction shown by arrow B which is a direction opposite to the rotating direction of the first rotating member 210.

[0045] At the same time, the stripping member 340 is rotated in a direction shown by arrow C which is a direction opposite to the rotating direction of the second rotating member 310, so a lateral uneven portion of the stripping member 340 comes into contact with the cut outer surface of the electric wire 10 and strikes the outer surface of the electric wire 10.

[0046] As the later uneven portion of the stripping member 340 strikes the cut outer surface of the electric wire 10, the cut outer insulating member and foil of the electric wire 10 are separated and removed from the electric wire 10.

[0047] The removal device of cable foil according to the present disclosure configured and operated as described above is intended to cut the outer insulating member and foil of the electric wire 10 by the foil cutting unit 200 and strip the cut foil by the foil stripping unit 300. Thus, it is very advantageously possible to reduce working time for removing the foil and to uniformly remove the outer insulating member and foil of the electric wire.

[0048] The removal device of the cable foil according to the preferred embodiment of the present disclosure has been described.

[0049] It should be understood that the above-described embodiment is illustrative and not restrictive, and the scope of the present disclosure is defined by the appended claims rather than by the description preceding them.
